The Travels of Marco Polo — Volume 1 by Marco Polo and da Pisa Rusticiano

1. Radde mentions as a rare crane in South Siberia _Grus monachus_,

called by the Buraits _Kará Togorü_, or “Black Crane.” Atkinson also speaks of “a beautiful black variety of crane,” probably the same. The _Grus monachus_ is not, however, jet black, but brownish rather. (_Radde, Reisen_, Bd. II. p. 318; _Atkinson. Or. and W. Sib._ 548.)
